ROTARY PUMP.

Specification of Letters Patent.

v Patented July 4, 1911.

Application filed January 19, 1909. SeriaI No. 473,161.

To all whom it may concern:

Be it known that I, BRocK'K. MOREHOUSE, a citizen of the United States, residing at Grand Junction, in the county of Mesa and State of Colorado, have invented a new and useful Improvement in Rotary Pumps, of which the following is a specification.

This invention relates to a rotary pump in which water is received upon one side'of the casing, and is drawn into an inner cylinder upon opposite sides of a revolving disk, through which work transversely sliding blades, which blades expel the water from the inner cylinder outwardly through the opposite side of the casing, the casing being divided by upper and lower, staggered partitions so that water is drawn through suitable ports into the inner cylinder in opposite directions, thereby enabling the sliding movement of the blades to maintain a continuous flow of water.

The invention consists of the novel features of construction hereinafter described, pointed out in the claims and shownin the accompanying drawings, in which,

Figure 1 is an end elevation, partly broken away and shown in section. Fig. 2 is a section on the line 2-2 of Fig. -1. Fig. 3 is a section on the line 33 of Fig. 2. Fig. 4 is 0 a section on the line 4-4 of Fig. 2. Fig. 5 is a plan View of the casing, the central top portion being broken out in order to illustrate the interior construction. Fig. 6 is a detail perspective view of a rotatable piston, shaft, and cylinder head, the parts being shifted from their normal position in order to more clearly show the construction of the parts.

In these drawings, 1 represents a suitable base upon which is mounted a cylindrical casing 2, the casing being eircumferentially cored out to form a substantially cylindrical chamber 3 which water chamber is interrupted by upper and lower staggered parti- -tions 3. Ports 4 and 4 afford communication between the upper portion of the water chamber and the interior of the casing, said ports being upon opposite sides of the wall 3 and also adjacent opposite ends of the casing as shown in Fig. 5. Similar lower ports 5 and 5 are provided at the bottom of the casing, said ports being also arranged upon opposite sides of the lower partition 3' and adjacent opposite ends of the casing. The partitions being off-set with respect to each other, the port 4 will be in alineme nt with the port 5 but will be-upon opposite.

sides of their respective partitions, and likewise the ports 4 and.5 substantially aline with each other, but are also'upon opposite sides of their respective partitions. This will appear more clearly when the direction of flow of water through the casing and throughthe cylinder is described. The casing is closed at eachend by a cylinder head 6 and each head carries a central extension 7 which forms a combined bearing and stutling box for the power shaft 8. This shaft is provided within the casing with a hub 9 upon which is fixed a disk 9* which disk is transversely slotted, the slots extending into the hub 9 and along the entire length of said hub as shown at 10. \Vorking in said slots and through the disk are movable blades 11, said blades being of such length that when one end of a blade-is flush with one end of the hub the other end of the blade will be flush with the opposite face-of the disk. This disk 9 divides the interior of the easing into right and left hand compartn'ients, one of which is in communication with the cored out portion 3 of the casing through the ports 4 and 5 and the other of-ivhich is in communication with said cored out portion through the ports 4 and 5. In order to prevent the circulation of water entirely around these compartments, each head (3 carries a curved abutment 12 which extends from the head 6 to the disk 9 and is cut out to bear upon the shaft 8. Each end of each abutment is also provided with two cani arms 13 which curve gradually from the inner face of said abutment to the head 6 by which said abutment is carried. These abutments and cams are disposed oppositely upon opposite heads, and it will therefore be obvious that as the disk 9 rotates the blades 11 by engagement with the cams 13 will be shifted back and forth through said disk. The hub 9 the disk 9 and blades 11 combined form a rotating piston. Upon opposite sides of the casing 2 and at right angles to the partition walls 3 are formed threaded extensions 14 into which suitable supply and discharge pipes are to be threaded.

It will be obvious that the abutments 12 and earns 13 may be so positioned that the piston may be rotated in either direction, so that either of the extensions 14 may be conthe Slots in the disk, being so shifted by the cams 13. Assuming that the hub 9 is rotating clock-wise as seen in Figs. 3 and 4, water will be drawnthrough the right hand extension linto'the water chamber 3 and will pass downwardly through the port 4 and will be caughtby the blades 11 which as they pass beneath the port 4 have been thrown to thatend of the casing, and the water will be carried around and expelled through the port 5 back into the water chamber 3 but upon the opposite side of the partitions 3, the abutment 12 carried by the head, 6 adjacent the ports 4 and 5 preventing the blades from forcing the water entirely around and back to the port 4. After the water has been expelled through the port 5 one of the cams 13 will shift the blades over to the opposite side of the piston and water will be drawn through the port 5 carried around by the blades and discharged through the port 4 and into the water chamber 3 and upon the same side of the partition 3 asthe water discharged through the port 5. It will be understood that as a. 1

portion of the blades are expelling water through port 4 others of the blades are carrying and expelling water through the the left-hand extension 14 and into the d1scharge pipe.

What -I claim is A rotary pum comprising a casing, a shaft extendin t erethrough, a hub on said shaft and within the casing, a disk fixed on said hub, said disk being transversely slotted, the slots extending into and extending the entire length of the hub, blades of .less length than the hub sliding in said slot, oppositely disposed abutments carried by the casing ends and extending respectively inwardly to the sides of the disk, cam arms carried by opposite ends of each abutment, said arms extending from the abutments to the casing ends, and shifting the blades, said casin being cored out to form a circumferentia water chamber, staggered off-set division walls dividing said water chambers into two parts said walls being placed respectively at the top and bottom of the easing, the casing having 'ports at the top, said ports opening between the water chamber and the exterior of the cylinder and upon opposite sides of the upper wall, and having bottom ports opening between the water chambers and the interior of the cylinder, and also upon opposite sides of the lower wall, as and for the purpose set forth.
